Matthias J. Sax commented on KAFKA-10608: ----------------------------------------- In general, this is a know issue, but it also depends what type of changes you make and if you name your operators. Can you elaborate what changes you refer to in particular? > Add support for rolling upgrade with topology changes > ----------------------------------------------------- > > Key: KAFKA-10608 > URL: https://issues.apache.org/jira/browse/KAFKA-10608 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Ashish Surana > Priority: Major > > We observed that if we modify the topology then we can't do rolling upgrade > as it seems all the instances should have exact same topology. > Everytime we upgrade topology we have to incur downtime, so we should explore > if this can be supported fully and if not fully then should be doable for > some subset of topology upgrades. -- This message was sent by Atlassian Jira (v8.3.4#803005)
